Abstract: 194,716. Krupp Akt.-Ges. Germaniawerft, F. March 13, 1922, [Convention date]. Driving-arrangements for screw propellers.-In the propeller shafts of ships driven by internal combustion engines resonance is prevented between the natural oscillations of the system and the vibrations due to torque variations by connecting a flywheel B to a point S on the shafting by means of an auxiliary elastic shaft. The point S is found by determining where the nodal point of the natural oscillations would be, if the system were used without the fly-wheel. The product of the mass of the fly-wheel and its distance from the point S is equal to the product of the equivalent engine mass and its distance from this point, and to the product of the propeller mass and its distance.

Abstract: 374,447. Coating with metals. ELECTRICAL RESEARCH PRODUCTS, Inc. 195, Broadway, New York, U.S.A.-(Assignees of Weinhart, H. W. ; 52, Georgian Court, Elizabeth, New Jersey, U.S.A.) March 9, 1931, No. 7298. Convention date, March 12, 1930. [Class 82 (ii).] A thin film of beryllium, which may be from 2 to 10 mils thick and either selfsupporting or as a coating on a metal body, is produced by volatilization and condensation. Pellets 18 of beryllium are welded on to a wire 17 of tungsten carried by wires 15 and copper discs 14 sealed in a re-entrant stem 11 of a glass vessel 10. A cup-shaped copper cathode 22, the bottom of which is to be coated, and its glass stem 24 are supported over the wire 17 by a metal stand 19. The whole is heated to about 400‹ C. while evacuated through a tube 12 and then an electric current is passed through the wire to increase the temperature gradually. When a sufficient deposit has been obtained the contents of the vessel 10 are removed with the stem 11, by melting at 110, the cathode 22 is replaced by a fresh one, and the parts reinserted and sealed at 110 ready for another operation. If a self-supporting film, tube, or corrugated sheet is required the article 22 is replaced by a mica former from which the deposit can be peeled, or by a former of salt, copper, or other material which can be subsequently dissolved. The method may be used for plating telephone or like diaphragms or ribbon, of the material sold under the registered Trade Mark " Duralumin," for sound recording. The beryllium sheets may be used as windows in X-ray tubes and in making acoustic measurements. Specifications 244,867, 293,723, [both in Class 39 (i), Electric lamps, Arc &c.], and 341,398, [Group XL], are referred to.

Abstract: 547,282. Aircraft retractable undercarriages. FAIREY AVIATION CO., Ltd., and EBEL, F. L. June 13, 1941, No. 7502. [Class 4] Mechanical means for locking a non-electrically operated, retractable landing gear in its down position are releasable electrically only when, during take-off, at least one of the undercarriage wheels has left the ground. As described, hydraulic apparatus for raising and lowering the undercarriage is controlled by a distributing valve linked to a rod x connected to a lever f shown in the undercarriage lowering position. Two toggle links t, u are connected respectively to a fixed pivot r and to a collar w slidable upon the rod x between abutments 13, 14 with interposed springs 11, 12. The toggle prevents movement of the rod x to initiate the retraction of the undercarriage unless a solenoid n is energised to move a lever p, q which raises the link t. Initial movement of the rod x to the extent permitted by the spring 12 causes a pivoted member 15 on the collar w to close a switch 17, 18 in the solenoid circuit, but the circuit is not completed until a switch j, k also is closed by the extension of an undercarriage leg as the landing wheel lifts clear of the ground when taking off. A switch j, k is provided for each leg and these switches may be in parallel or in series. When the lever f is moved right over to raise the undercarriage the member 15 moves clear of the switch mechanism 16, 17 and the circuit is left open.

Abstract: 360,782. Microscopes. ZEISS, C. [Firm of], Carl Zeiss-Strasse, Jena, Germany. March 12, 1931, No. 7616. Convention date, March 24, 1930. [Class 97 (i).] An illuminating appliance providing dark ground illumination of one colour and light ground illumination of a different colour consists of a condenser b provided with an iris diaphragm c, and colour filters for producing differently coloured lights in the central and outer parts of the pencil of illuminating rays. The filters are mounted in a pivoted support f below the condenser and comprise an annular red filter g surmounted by a smoked glass h, and a blue filter l mounted in a tube i which is fitted in the central aperture in the filter g. Directly beneath the filter l and immediately above a dispersing filter o of frosted glass is an iris diaphragm m and at the lower end of the tube i is an iris diaphragm p. The diaphragm p controls the brilliancy of illumination of the filter o and the diaphragm m controls the aperture of the said filter. The filter l may also be surmounted by a smoked glass r. Rays passing through the filter g and the condenser leave the latter at such an angle as to pass outside the front lens of the microscope objective, and therefore provide the dark ground illumination, while the light ground illumination is produced by the rays passing through the filter l.
